The Magdi Yacoub Institute Report of the Trustees

Objectives of The Magdi Yacoub Institute

The objectives in the Memorandum of Association are:

“To carry out research into all aspects of human heart, lung and other disease including prevention, treatment and rehabilitation, for the benefit of the public by:

(i) undertaking and promoting research (and making the useful results thereof publicly available) in relation to cardiac and transplant surgery, human heart valves and tissue engineering, circulatory support, immunology of heart and lung disease, biochemistry of heart failure, biology of human blood vessels, molecular aspects of heart disease, metabolism of the human heart and lung, transplant medical management, genetic research (in all its forms) and any other medical matter which might effect or affect an improvement in human health and wellbeing;

(ii) relieving persons suffering from heart or other diseases by enabling transplant and other operations to be carried out and associated care and treatment to be provided at Harefield Hospital or at such other site as may be convenient or appropriate;

(iii) providing and constructing amenities, equipment and facilities within the Harefield Hospital site or any linked establishments or other appropriate site or sites for the treatment and research into care and relief of persons suffering from heart or other disease who may require or who are to undergo or who have undergone transplant or other surgery; and

(iv) "any other means which appear convenient or appropriate from time to time."

Charity’s Aims

The aim of the Magdi Yacoub Institute is to undertake and advance world class research into the causes and nature of heart disease, including its prevention and treatment for the benefit of humanity. Working in collaboration with other public and private organisations, as well as individuals from across the world, the Institute raises and receives funding to finance its operations and activities. The Institute initiates and promotes innovative research programmes, organising scientific leadership and direction, facilities, staff, equipment and research grants in pursuit of its aims and visions.

Objectives for the year

The objectives for the year were to continue to progress our overall research programme focused around: heart failure, tissue engineering and transplantation. The work streams in this areas are detailed below in our activities.

Charity’s strategies and significant activities

The main activities have been to progress research and to review a structure to have scientific alliances with key institutes to advance the science. Alongside these work activities:

Tissue Engineering. Our research in tissue engineering is aimed at the development of a viable cardiac valve capable of reproducing the sophisticated functions of the normal valve. This research is based on understanding the specific cellular and molecular characteristics of the component parts, during development and in the adult, on examining the properties of stem cells and their suitability for deriving valve tissue and of examining the optimal cellular environment and scaffolds for engineering valve tissue.

Transplantation . Transplant related research continues in addressing several current issues, including chronic rejection, the role of endothelial cells in rejection, metabolic function in xenotransplantation and importantly organ resuscitation.

Valves. Work on the development of the Harefield Composite Component Valve (HCCV) continues to progress well. Much of the work during has centred on converting the labatory production protocols to make the valve, into protocols that meet the standards required to produce a valve for FDA approval and clinical use. We continue to have a number of visiting undergraduate and work experience students working in the laboratory over the course of the year who have contributed to a number of different projects.

The Magdi Yacoub Institute Report of the Trustees

Charity’s strategies and significant activities (continued)

Valve Calcification Project. As per the previous year work continues with our in vitro organ culture model of valve calcification. This model will allow further studies into the mechanisms the initiate and progress the calcification of heart valves and assessment of drugs that may be used to treat the disease. This method has potential advantages over other published methods of looking at valve calcification due to the use of intact (porcine) valve tissue.

Volunteer Help

The Magdi Yacoub Institute does utilise volunteer help. Friends of MYI committee, the Next Generation raise awareness of the charity and support at events.

Grant making policy

The Magdi Yacoub Institute supports research by directly employing staff as well as making awards to the National Heart & Lung Institute ("NHLI") (Imperial College) for the cost of consumables for the staff engaged in research at the Heart Science Centre, Harefield. Support is also given to facilitate collaboration with research with the Aswan Heart Centre / Magdi Yacoub Foundation and tissue engineering, genetic studies into cardiomyopathy and developmental dynamics.

REVIEW OF ACHIEVEMENTS AND FINANCIAL ACTIVITY

The Tissue Engineering project continues to make excellent progress. Further implants in large animals are scheduled to continue testing the valve, and a paper has been well received and has opened discussions with the FDA.

The team continue to have their papers published in leading peer reviewed journals and the inhouse journal GCSP published a full compliment during the last financial year. The top 5 citing institutions are Imperial College London, Harvard University, Mayo Clinic, INSERM and National Institute of Health. The Journal averages 10 citations per manuscript.

The Friends of MYI' meet regularly and held several sucessful events which raised vitual funds for the charity.

The team continues to publish papers in leading journals. The Institute has received substantial donations to support the advancement of research from personal donors.

Sucessful grant received for the study of mechanisms involved in heart valve calcification. Use of an Organ Culture Model to Investigate the Role of Type 2 Nitric Oxide Synthase and Hypoxia-Induced Factor 1 in Aortic Valve Calcification.

Research Support and Equipment purchases

Funding was made available for the running and maintenance of the MYI laboratories, no significant equipment has been purchased.

Results for the year are shown in the Statement of Financial Activities on page 11.

Total income for the year was £2,195,619 (2024: £1,111,931) and expenditure was £1,733,417 (2024: £1,562,316). The Charity has made a surplus of £462,202 (2024: deficit of £450,385). As a direct result of this, at the year end total unrestricted funds were £4,406,826, including £3,583,132 in designated funds representing the net book value of fixed assets held by the charity and restricted funds of £680,833. Total unrestricted and restricted funds of £5,087,659 (2024: £4,625,457).

The Magdi Yacoub Institute Report of the Trustees

Research Support and Equipment purchases (continued)

The principal sources of funding during the year were from:

Reserves Policy

The Institute’s policy with regard to reserves is to make suitable investment in ongoing development of the charity whilst maintaining adequate funds to deal with current and medium term needs. Free reserves at the year end excluding designated funds and restricted funds are £823,694 (2024: £768,344).

The Trustees wish to have a minimum of £450,000 in reserves to cover closure commitment. Free reserves are above the level set by the trustees and they are satisfied with the current situation.

Fundraising policy

The Magdi Yacoub Institute has a cost of raising funds in the financial statements in relation to generating income from donors. The charity does not utilise external professional fundraisers or commercial participators to carry out fundraising activity and does not engage in face-to-face or telephone fundraising. We aim to build and maintain solid partnerships with our supporters and do not undertake activities to raise funds from those that could be classified as “vulnerable people”. Any approach to fundraising would take account of the Code of Fundraising Practice issued by the Fundraising Regulator. The Magdi Yacoub Institute has received no complaints about its fundraising activities either during the financial year or subsequently.

Risk Management

In March 2025, the Trustees completed its annual review of the Institute's risk management strategy in accordance with the requirements of the SORP. Each identified risk is classified into one of the following categories:

Governance: Trustee appointments, decision making and possible conflicts of interest. Operational: Disaster recovery. Health & Safety issues.

Regulatory Framework: Compliance with existing legislation and regulations. External: Relationship with the NHS and Imperial College.

Financial: Reduction in investment income, donations and grants. Fundraising issues: Loss of key supporters. Appropriate fundraising strategy.

In the course of the review, the Trustees have determined the major risks to which the Institute is exposed, the potential impact if an individual risk materialises, and which mitigating action is to be taken, by whom, in order to reduce the risk to a level which the Trustees consider to be acceptable. The position is recorded in a risk register which is used by management and will continue to be formally reviewed annually.

Public Benefit

The Trustees have considered the Charity Commissioner's general guidance on public benefit when reviewing the Institute's aims and objectives and planning future activities. The aim of the Institute is to undertake and advance world class research into the causes and nature of heart disease, including its prevention and treatment, for the benefit of humanity. To this end, advances in research are published and available to others with similar aims.

The Institute collaborates with other organisations undertaking research in third world countries and assists in advancing their research capability. There are no exclusions to those who can benefit from the results of the Institute's research and beneficiaries will be worldwide. There are no private benefits gained, other than incidental, by those engaged in research at the Institute.

Plans for the Future

For the year to 31st March 2026, the Trustees have set the following key performance indicators (KPI):

Our aim remains to progress research projects and this data is being gathered. The team are progressing well with grant submissions and articles being citied in renowned journals.

Disclosure of Information to Auditors

So far as the trustees are aware, there is no relevant audit information of which the company's auditors are unaware. The trustees have taken all the steps that they ought to have taken as trustees in order to make themselves aware of any relevant audit information and to establish that the company's auditors are aware of that information.

Statement of Trustees' Responsibilities

The trustees (who are also directors of The Magdi Yacoub Institute for the purposes of company law) are responsible for preparing the Trustees' Report and the financial statements in accordance with applicable law and United Kingdom Generally Accepted Accounting Practice. Company law requires trustees to prepare financial statements for each financial year which give a true and fair view of the state of affairs of the Charitable company and of the incoming/outgoing resources and application of resources, including the income and expenditure, of the charitable company for that period. In preparing those financial statements, the directors are required to:

The trustees are responsible for keeping proper accounting records that disclose with reasonable accuracy at any time the financial position of the charitable company and enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the charitable company and the group and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

These accounts have been prepared in accordance with the special provisions relating to small companies within Part 15 of the Companies Act 2006.

Independent Auditors Report to the Trustees of The Magdi Yacoub Institute

Opinion

We have audited the financial statements of The Magdi Yacoub Institute (‘the charitable company’) for the year ended 31 March 2025 which comprise the Statement of Financial Activities, the Balance Sheet, the Statement of Cash Flows and notes to the financial statements, including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including FRS 102 ‘The Financial Reporting Standard Applicable in the UK and Ireland’ (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:

• give a true and fair view of the state of the charitable company’s affairs as at 31 March 2025 and of its incoming resources and application of resources, including its income and expenditure, for the year then • have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and

• have been prepared in accordance with the requirements of the Companies Act 2006.

Basis for opinion

We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs(UK)) and applicable law. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the audit of financial statements section of our report. We are independent of the Corporation in accordance with the ethical requirements that are relevant to our audit of the financial statements in the UK, including the FRC’s Ethical Standard, and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Conclusions relating to going concern

In auditing the financial statements, we have concluded that the trustees’ use of the going concern basis of accounting in the preparation of the financial statements is appropriate.

Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.

Other information

The other information comprises the information included in the annual report, other than the financial statements and our auditor’s report thereon. The trustees are responsible for the other information. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether there is a material misstatement in the financial statements or a material misstatement of the other information. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.

We have nothing to report in this regard.

Page: 7

Independent Auditors Report to the Trustees of The Magdi Yacoub Institute

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of the audit:

• the information given in the trustees’ annual report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

Matters on which we are required to report by exception

In the light of the knowledge and understanding of the company and its environment obtained in the course of the audit, we have not identified material misstatements in the trustees’ annual report.

We have nothing to report in respect of the following matters where the Companies Act 2006 requires us to report to you if, in our opinion:

• adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or

• the trustees were not entitled to prepare the financial statements in accordance with the small companies regime and take advantage of the small companies exemption in preparing the Trustees’ Annual Report and from preparing a Strategic Report.

Responsibilities of trustees

As explained more fully in the trustees’ responsibilities statement set out on page 6, the trustees (who are also the directors of the charitable company for the purposes of company law) are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the trustees determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the trustees are responsible for assessing the charitable company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the trustees either intend to liquidate the charitable company or to cease operations, or have no realistic alternative but to do so.

Auditor’s responsibilities for the audit of the financial statements

Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements.

As part of an audit in accordance with ISAs (UK) we exercise professional judgement and maintain professional scepticism throughout the audit. We also:

• Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

Page: 8

Independent Auditors Report to the Trustees of The Magdi Yacoub Institute

Auditor’s responsibilities for the audit of the financial statements (continued)

• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purposes of expressing an opinion on the effectiveness of the charitable company’s internal control.

• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the trustees.

• Conclude on the appropriateness of the trustees’ use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the charitable company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the charitable company to cease to continue as a going concern.

• Evaluate the overall presentation, structure and content of the financial statements, including the disclosures, and whether the financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

Explanation as to what extent the audit was considered capable of detecting irregularities, including

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below.

The objectives of our audit in respect of fraud, are; to identify and assess the risks of material misstatement of the financial statements due to fraud; to obtain sufficient appropriate audit evidence regarding the assessed risks of material misstatement due to fraud, through designing and implementing appropriate responses to those assessed risks; and to respond appropriately to instances of fraud or suspected fraud identified during the audit. However, the primary responsibility for the prevention and detection of fraud rests with both management and those charged with governance of the charitable company.

Our approach was as follows:

• We obtained an understanding of the legal and regulatory requirements applicable to the company and considered that the most significant are the Companies Act 2006, the Charities Act 2011, UK financial reporting standards as issued by the Financial Reporting Council and UK taxation legislation.

• We obtained an understanding of how the charitable company complies with these requirements by discussions with management and those charged with governance.

• We assessed the risk of material misstatement of the financial statements, including the risk of material misstatement due to fraud and how it might occur, by holding discussions with management and those charged with governance.

• We inquired of management and those charged with governance as to any known instances of noncompliance or suspected non-compliance with laws and regulations.

• Based on this understanding, we designed specific appropriate audit procedures to identify instances of non-compliance with laws and regulations. This included making enquiries of management and those charged with governance and obtaining additional corroborative evidence as required.

Independent Auditors Report to the Trustees of The Magdi Yacoub Institute

Explanation as to what extent the audit was considered capable of detecting irregularities, including fraud (continued)

There are inherent limitations in the audit procedures described above. We are less likely to become aware of instances of non-compliance with laws and regulations that are not closely related to events and transactions reflected in the financial statements. Also, the risk of not detecting a material misstatement due to fraud is higher than the risk of not detecting one resulting from error, as fraud may involve deliberate concealment by, for example, forgery or intentional misrepresentations, or through collusion.

Use of our report

This report is made solely to the charitable company's members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the company’s members those matters we are required to state to them in an auditor’s report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to any party other than the charitable company and charitable company's members as a body, for our audit work, for this report, or for the opinions we have formed.

The financial statements have been prepared in sterling, which is the functional currency of the entity. Monetary amounts in these financial statements are rounded to the nearest pound.

Going Concern

The trustees have assessed whether the use of the going concern basis is appropriate and have considered possible events or conditions that might cast significant doubt on the ability of the company to continue as a going concern. The trustees have made this assessment for a period of at least one year from the date of approval of the financial statements. Donation income is the Institute's main source of income and often is reliant on large ad-hoc donations from donors from the wider network of the Institute's founder Professor Yacoub. The trustees have prepared a cash flow forecast covering a period of at least twelve months from the date of approval of these accounts that only takes into account confirmed income and considered howe expenditure could be managed if further donations were no forthcoming. Based on this they have concluded the Institute has adequate resources to continue in operation in this period and therefore the company continues to adopt the going concern basis in preparing its financial statements.

Income

Donations, Legacies and similar income

All income is recognised when there is entitlement to the funds, the receipt is probable and the amount can be measured reliably.

Legacies are recognised following probate and once there is sufficient evidence that receipt is probable and the amount of the legacy receivable can be measured reliability. Where entitlement to a legacy exits but there is uncertainty as to its receipt or the amount receivable, details are disclosed as a contingent asset until the criteria for income recognition are met.

Grants Receivable

Grants receivable are credited to the Statement of Financial Activities (SOFA) in the year for which they are received. Deferred income represents amounts received for future periods and is released to incoming resources in the period for which it has been received.

Expenditure

Expenditure is accounted for on an accruals basis and are recognised when there is a legal or constructive obligation to pay for the expenditure.

Expenditure on operational programmes is recognised in the period in which it is incurred. A designated fund is established for expenditure, which has been committed to projects, but remains unspent at the year end.

1 Accounting Policies (continued)

Charitable expenditure

These comprise of research costs. It includes both costs that can be allocated directly to such activities and those costs of an indirect nature necessary to support them.

Allocation of costs

All costs are allocated between expenditure categories of the SoFA on a basis to reflect the use of the resource. Costs relating to a particular activity are allocated directly, others are apportioned on a direct cost basis.

Governance costs

These include those costs associated with meeting the constitutional and statutory requirements of the charity and include the audit fees and the costs linked to the strategic management of the charity.

Stock

Stock is stated at the lower of cost and net realisable value.

Capitalisation and Depreciation of Tangible Fixed Assets

All assets costing more than £500 are capitalised at cost.

Depreciation is provided on all tangible fixed assets at rates calculated to write off their cost over their expected useful lives as follows:

Freehold Land Land is not depreciated Freehold Buildings 2% straight line Furniture, Fittings and Equipment 25% reducing balance Machinery 25% reducing balance

Financial Instruments

Cash and cash equivalents

Cash and cash equivalents include cash at banks and in hand and short term deposits with a maturity date of three months or less.

Debtors and creditors

Debtors and creditors receivable or payable within one year of the reporting date are carried at their at transaction price. Debtors and creditors that are receivable or payable in more than one year and not subject to a market rate of interest are measured at the present value of the expected future receipts or payment discounted at a market rate of interest.

Pension

The organisation operates a defined contribution scheme where costs are charged to the Statement of Financial Activities as they become due.

Taxation

The charity is exempt from corporation tax under sections 466-497 of the Corporation Taxes Act 2010 as all its income is applied to charitable purposes.

The Magdi Yacoub Institute Notes to the Financial Statements For the year ended 31st March 2025

1 Accounting Policies (continued)

Raising Funds

These include the salaries, direct expenditure and overhead costs of the staff who promote fundraising including events.

Fund Accounting

Funds held by the charity are:

Unrestricted general funds

These are funds which can be used in accordance with the charitable objects at the discretion of the trustees.

Designated Funds

These funds have been earmarked by the trustees for a particular purpose.

Restricted Funds

These are funds that can only be used for particular restricted purposes within the objects of the charity. Restrictions arise when specified by the donor or when funds are raised for particular restricted purposes.

Foreign Currencies

Transactions in foreign currencies are recorded using the rate of exchange ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are translated using the rate of exchange ruling at the balance sheet date. Gains or losses on transactions are included in the Statement of Financial Activities.

Critical accounting estimates and areas of judgement

Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances.

(a) Useful economic lives of tangible assets

The annual depreciation charge is sensitive to changes in the estimated useful economic lives of the assets. Useful economic lives are re-assessed annually and are amended where necessary to reflect current estimates based on the physical condition of the assets. See note 1 accounting policies for the useful economic lives of tangible assets.
